Could not download the file to my upload directory using CURL - php

Question

i am trying to download the source file bellow using curl, but it is only creating destination file with 0 bytes, not downloading the original file and write the resource data. How can i solve this problem. I tried a example from this link: http://www.w3bees.com/2013/09/download-file-from-remote-server-with.html . But it also give the same result.
Anybody can help? my code is:
if(isset($_POST[$data_file_name_url])){
$source = 'http://mr-greens-class.wikispaces.com/file/messages/Calender.ics';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $source);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSLVERSION,3);
$data = curl_exec ($ch);
$error = curl_error($ch);
curl_close ($ch);
$destination = $dir.'/test.ics';
$file = fopen($destination, "w+");
fputs($file, $data);
//file_put_contents($destination, $data);
fclose($file);
}

You should remove SSLVERSION if not use (your URL start with http, so I assume it's not SSL)
$path = 'myfile.ics';
$final_url = 'http://mr-greens-class.wikispaces.com/file/messages/Calender.ics';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $final_url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
//curl_setopt($ch, CURLOPT_PORT, 80);
curl_setopt($ch, CURLOPT_HEADER, 0);
// sometimes needed to prevent problem by bot filtering
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/36.0.1985.103 Safari/537.36');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$data = curl_exec($ch);
if($data == false) {
$errno = curl_errno($ch);
$error_message = curl_error($ch);
//error_log( "cURL error ({$errno}):\n<br/> {$error_message}");
}
curl_close($ch);
file_put_contents($path, $data);
